Not getting undeliverable notice

Hi,

I have a web application where someone fills in a contact form. My code sends an auto-response to the user. I've been testing non-existant email accounts but am not receiving an undeliverable message. I know the auto-response is definitely sending as I've bcc'd my own email in and receive that.

Re: Not getting undeliverable notice

It really depends on what you mean by "non-existant email accounts" @robbied If you are just picking randomuser546745@gmail.com even though that email address may not exist I wouldn't expect GMail to send out a courtesy undeliverable. Servers would be sending out responses all day and could/would be bombarded if that were the case. Email servers that I run wouldn't inform you that you got an email address wrong or to a non-existent address. I just usually define a catchall address to swallow all of those email to non-existant email accounts. I'd just concentrate on the fact that you received the message. You can always check using real addresses. I hope that helps?

...turns out that my two cents is worth less or more depending on the current exchange rate.

Re: Not getting undeliverable notice

The reality is servers will treat different requests differently. It is possible that you individual email address sending from your @yahoo.com or @Gmail.com (or whatever) is treated differently to a request coming in from a contact form which is basically a bot. I don't think that you should anticipate a bounceback. I guess I don't get why you feel like you need to get undeliverable messages back?

Re: Not getting undeliverable notice

I'm having the same issue and the reason it's important that people get an undeliverable/bounceback message when they've incorrectly entered an email address is simple. If they don't, they believe their email HAS been delivered and expect a response.

I would still like to know how to turn this option on if it exists for cPanel email.
